United States Patent O 3,116,751 FLOOR DRAlN STANDPIPE Robert C. Hamilton, South Bend, Ind., assignor to Jackel, Inc., South Bend, Intl., a corporation of Indiana Filed Jan. 4, 1962, Ser. No. 164,239 2 Claims. (Cl. 137-362) This invention relates to a novel and useful floor drain stan-dpipe land more specifically to a standpipe which is primarily designed for the punpose of providing a means whereby the conventional type of floor drain may be utilized as both a means Ifor draining liquids from a floor surface and alternately as a standpipe drain for draining the discharge of washing machines land the like whose outlet conduits must have their outlet ends elevated above the water level in the washing machine.

Many types of oor drain standpipes have been previously hereto-fore provided but most have been constructed in a manner similar to the -st-andpipe drain disclosed in U.S. Patent No. 1,951,632 which includes an upstanding tubular standard whose lower end is externally threaded for threaded engagement with the upper end of a door drain and which is also provided with outlet openings which open through the externally threaded portion of the standpipe. With this type of standpipe, the outlet openings are elevated above the upper end of the floor drain pipe by turning the standpipe a sufficient number of turns to raise the `outlet openings above the upper end of the oor drain pipe in which the lower end of the standard -is threadedly engaged and if the standard is to be used as a drain for a washing machine outlet conduit and the like, it is necessary to lower the standp-ipe relative to the floor drain pipe by vturning the standard a sufficient number of turns to move the apertured portion of the externally threaded lower end of the standard into the internally threaded upper end of the floor drain pipe. While this type of standpipe operates very effectively, because of the necessity to raise and lower the outlet openings forme-d therein relative to the floor drain pipe with which it is engage and into and out of registry with the upper end of the floor drain pipe, considerable time and effort must be expended when it is desired to change this type of standard from a oor draining position to an appliance draining position.

Accordingly, it is the main object of this invention to provide a floor drain standpipe which is constructed in a manner whereby it may be readily converted from one draining position to the other almost instantaneously.

A further object of this invention, in accordance with the immediately preceding object, is to provide a floor drain standpipe which may be secured to the upper end of a iioor drain pipe in the conventional manner by threaded engagement therewith but which is constructed in a manner whereby only a minimum amount of threaded engagement is required to secure the floor drain standpipe to the oor drain pipe.

Another object of this invention is to provide a licor drain standpipe which will conform to conventional forms of manufacture, be of simple construction and easy to use so as to provide a device that will be economically feasible, ,long lasting and relatively trouble free in operation.

These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation `as more -fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerels refer to like parts throughout, and in which:

FIGURE 1 is a perspective view of the floor drain standpipe of the instant invention with portions thereof being broken away and shown in section;

FIGURE 2 is a fragmentary vertical sectional view 3,116,751 Patented Jan. 7, 1964 ICC taken through a section of concrete flooring having a oor drain therein and showing the lower end of the standpipe of the instant invention secured in the upper end of the floor drain; and

FGURE 3 is a horizontal sectional view taken substantially upon the plane indicated by the section line 3 3 of FIGURE 2.

Referring now more specifically to the drawings and to FGURE 2 in particular, it will be noted that a floor construction generally referred to by the reference numeral 1t) is provided with an upwardly opening recess 12 into which the upper end of an internally threaded floor drain pipe 14 opens. Only a short distance of the upper end of the floor drain pipe is internally threaded as at 16 and it will be seen that the floor drain standpipe of the instant invention is generally designated by the reference numeral 13. The floor drain standpipe 1S includes an elongated upright tubular standard 2d whose lower end has a diametrically enlarged lower end section generally referred to by the reference numeral 22 secured thereto in any convenient manner such as by welding 24. The diametrically enlarged lower end portion is externally threaded at its lower terminal end portion 26 as at 28 and includes a generally radially outwardly projecting annular shoulder 3d whose lower face 32 -is adapted to abut the upper end of the oor drain pipe 14 in which the terminal end portion 26 is threadedly engaged. The upper surface 3d of the shoulder 3@ comprises thrust bearing means for the lower end of a valve collar assembly generally referred to by the reference numeral 36 which is rotatably journaled on the adjacent portions of the standard 2% and the diametrically enlarged lower end portion 22.

The movable valve collar 36 includes an outer body portion 33 which is generally cylindrical and an inner cylindrical seal member 4d whose upper end is turned inwardly as at ft2 and is disposed in fluid sealing contacting relation with the outer surfaces of the standard 2t) as at da. It is to be noted that the seal member itl is to be constructed of a material which will not be adversely affected by cleaning materials such as bleach and detergents and is adapted to move with collar 36.

A stop collar generally referred to by the reference numeral dit is secured to the standard 20 above the valve collar 36 in any convenient manner and the stop collar or ring 48 is provided with a radially outwardly projecting abutment member Stb which is disposed for engagement with a stop member 52 which is carried by and projects upwardly from the upper end of the valve collar 36.

It may be observed that the diametrically enlarged lower end portion 22 includes a plurality of generally radial openings 54 which are spaced circumferentially about the lower end portion 22 and that the valve collar 36 includes a plurality of generally radial passages 56 which may be simultaneously moved into and out of registry with the openings 54.

In operation, if it is desired to use the standpipe 18 as a drain for an appliance such as a washing machine, the passages 56 may be moved out of registry with the openings 54 by rotating the valve collar 36 relative to the standard 18. However, when it is desired to drain fluids from the floor 16, the valve collar 36 may be rotated relative to the standard 18 in order to move the passages 56 into registry with the openings 54. It will be noted that the seal member 4t) is disposed in fluid tight sealing engagement with the outer surfaces of the diametrically enlarged lower end portion 22 disposed adjacent the openings 54 and accordingly, that fluids passing downwardly through the standard 18 when the passages 56 are not registered with the passages 54 will not be capable of owing outwardly through the passages 56 and onto the upper surface of the floor 1t). Additionally,

it will be noted that an inwardly projecting annular seal 60 is carried by the lower end of the terminal end portion 26 and that the seal 60 is adapted to have a spherical ball oat valve 62 disposed in iiuid tight sealing engagement therewith. The spherical float valve 62 is utilized to prevent water and the like from backing up through the floor drain pipe 14 and out of the standard 13. As water rises in the floor drain pipe 14 due to back pressure, the spherical valve 62 will be moved into fluid tight Sealing engagement with the annular seal 60.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.

What is claimed as new is as follows:

1. A oor drain standpipe for securement to the open upper end of a oor drain pipe, said standpipe including an elongated upright tubular standard whose lower end includes a terminal end portion having means adapted for securement to the upper end of said drain pipe, the lower end of said standard above said terminal end portion including inlet opening means, and movable valve means carried by said standard for selectively opening and closing said opening means, said movable valve means comprising a valve collar journaled on said standard and including passage means selectively registrable with said opening means, said standard including stop means disposed above said collar, said collar including abutment means projecting upwardly therefrom and engageable with said stop means to establish a limit of rotation of said collar relative to said standard, said stop means comprising a stop collar carried by said standard and also comprising thrust bearing means for the upper end of said collar and said standard between said collar and said terminal end portion including an outwardly projecting and upwardly facing shoulder formed integral therewith and comprising thrust bearing means for the lower end of said collar.
